Bosch is leading a consortium in a German government-funded project to develop a direct injection system for monovalent natural gas engines—i.e., engines that run exclusively on CNG. Today’s CNG vehicles are generally bivalent, running on gasoline and CNG with engines designed for gasoline direct injection.

Researchers at the University of California, Riverside’s Bourns College of Engineering have used waste glass bottles and a low-cost chemical process to fabricate nanosilicon anodes for high-performance lithium-ion batteries. An open access paper describing the research was published in the Nature journal Scientific Reports.

In a 2010 paper published in the ACS journal Nano Letters , researchers from Nanotek Instruments, Ångström Materials and Dalian University of Technology (China) observed that graphene is an outstanding candidate electrode material for supercapacitors. This is also an advantage because cooling systems can be downsized or removed altogether.

The EU goal is to introduce the WLTP by 2017 if possible and no later than 2020 to coincide with the 95 g/km requirement. This means that in addition the power demand is more difficult to achieve with engine downsizing and transmission down-speeding alone. the Worldwide harmonized Light vehicles Test Procedures (WLTP).
